Cr(VI)　pollution　in　water　bodies　is　very　harmful　to　human　health　and　the　environment.　Therefore,　it　is　necessary　to　remove　Cr(VI)　from　water.　In　this　study,　the　composite　(FP-nZVI)　was　prepared　by　loading　nano-zero-valent　iron　(nZVI)　onto　cellulose　filter　paper　(FP)　using　a　liquid-phase　reduction　method　to　improve　the　dispersibility　and　oxidation　resistance　of　nZVI.　In　batch　experiments,　the　effects　of　iron　loading　of　FP-nZVI,　initial　concentration　of　Cr(VI),　temperature,　and　pH　on　Cr(VI)　removal　were　particularly　investigated.　The　maximum　removal　rate　of　98.6%　was　achieved　at　25　°C,　pH　=　5,　initial　concentration　of　Cr(VI)　of　20　mg/L,　and　FeCl3·6H2O　solution　concentration　of　0.8　mol/L.　The　removal　of　Cr(VI)　by　FP-nZVI　conformed　to　a　pseudo-second-order　kinetic　model　and　Langmuir　isotherm　model.　The　mechanism　of　Cr(VI)　removal　was　a　multi-step　removal　mechanism,　involving　adsorption,　reduction,　and　coprecipitation.　Column　experiments　investigated　the　effect　of　flow　rate　(1　mL/min,　3　mL/min,　and　5　mL/min)　on　Cr(VI)　removal.　We　found　that　increasing　flow　rate　slightly　decreased　the　removal　rate　of　Cr(VI).　The　transport　of　Cr(VI)　in　composite　porous　media　was　simulated　using　HYDRUS-1D,　and　the　results　show　that　the　two-site　model　can　well　simulate　the　reactive　transport　of　Cr(VI).　This　study　may　provide　a　useful　reference　for　the　remediation　of　groundwater　contaminated　with　Cr(VI)　or　other　similar　heavy　metals　using　FP-nZVI.　©　2023　by　the　authors.
